  • DOAG 2012 and Educause 2012

    - by Chris Kawalek
    Oracle understands the value of desktop virtualization and how customers have really embraced it as a top tier method to deliver access to applications and data. Just as supporting operating systems other than Windows in the enterprise desktop space started to become necessary perhaps 5-7 years ago, supporting desktop virtualization with VDI, application virtualization, thin clients, and tablet access is becoming necessary today in 2012. Any application strategy needs to have a secure mobile component, and a solution that gives you a holistic strategy across both mobile and fixed-asset (i.e., desktop PCs) devices is crucial to success. This means it's probably useful to learn about desktop virtualization, even if it's not in your typical area of responsibility. A good way to do that is at one of the many trade shows where we exhibit. Here are two examples:  DOAG 2012 Conference + Exhibition The DOAG Conference is fast approaching, starting November 20th in Nuremberg, Germany. If you've been reading this blog for a while, you might remember that we attended last year as well. This conference is fantastic for us because we get to speak directly to users of Oracle products. In many cases, those DBAs, IT managers, and other infrastructure folks are looking for ways to deal with the burgeoning BYOD model, as well as ways of streamlining their standard desktop and access technologies. We have a couple of sessions where you can learn a great deal about how Oracle can help with these points. Session Schedule (look under "Infrastruktur & Hardware") The two sessions focused on desktop virtualization are: Oracle VDI Best Practice unter Linux (Oracle VDI Best Practice Under Linux) Virtual Desktop Infrastructure Implementierungen und Praxiserfahrungen (Virtual Desktop Infrastructures Implementations and Best Practices) We will also have experts on hand at the booth to answer your questions on using desktop virtualization. If you're at the show, please stop by and say hello to our team there! Educause 2012  Another good example is Educause. We've gone the last few years to show off a slough of education oriented applications and capabilities in the Oracle product portfolio. And every year, we display those applications through Oracle desktop virtualization. This means the demonstration can easily be setup ahead of time and replicated out to however many "demo pods" that we have available. There's no need for our product teams to setup individual laptops for demos -- we can display a standardized Windows desktop virtual machine with their apps all ready to go on a whole bunch of devices like your standard trade show laptop, our Sun Ray Clients, and iPad. Educause 2012 just wrapped, so we're sorry we missed you this year. But there is always next year! Until then, here are a few pictures from this year's show: You can also watch this video to see how Catholic Education Australia uses Oracle Secure Global Desktop to help cope with the ever changing ways that people access their applications.  -Chris

  • JUDCon 2013 Trip Report

    - by reza_rahman
    JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

  • The Social Business Thought Leaders

    - by kellsey.ruppel
    Enterprise Gamification, Big Data, Social Support, Total Customer Experience, Pull Organizations, Social Business. Are these purely the latest buzzwords to enter the market or significant trends that companies should keep an eye on? Oracle recently sponsored and presented at the 5th Social Business Forum, one of the largest European events on the use of social media as a business tool and accelerator. Through the participation of dozens of practitioners, experts and customer success stories, the conference demonstrated how a perfect storm of technology, management and cultural change is pushing peer-to-peer conversations deep into business processes. It is clear that Social Business is serving as a new propellant of agility, efficiency and reactivity. According to Deloitte and MIT what we have learned to call Social Business is considered important in the next 3 years by 86% of managers (see Social Business: What Are Companies Really Doing?, MIT Sloan Management Review and Deloitte). McKinsey further estimates the value that can be unlocked in terms of knowledge-worker productivity, consumer insights, product co-creation, improved sales, marketing and customer service up to $1300B (See The social economy: Unlocking value and productivity through social technologies, McKinsey Global Institute). This impacts any industry, with the strongest effects seen in Media & Entertainment, Technology, Telcos and Education. For those not able to attend the Social Business Forum and also for the many friends that joined us in Milan, we decided to keep the conversation going by extracting some golden nuggets from the perspective of five of the most well-known thought-leaders in this space. Starting this week you will have the chance to view: John Hagel (Author of the Power of Pull and Co-Chairman Center for the Edge at Deloitte & Touche) Christian Finn (Senior Director, WebCenter Evangelist at Oracle) Steve Denning (Author of The Radical Management and Independent Management Consulting Professional) Esteban Kolsky (Principal & Founder at ThinkJar) Ray Wang (Principal Analyst & CEO at Constellation Research) Stay tuned to hear: How pull organizations are addressing some of the deepest challenges impacting the market. How to integrate social into existing infrastructure and processes. How to apply radical management to become more agile and profitable. About the importance of gamification as an engagement lever. The first interview with John Hagel will be published tomorrow. Don't miss it and the entire series!

  • It is CX a new concept?

    - by Isabel F. Peñuelas
    The Marketing Industry and the Web Industry are talking about CX since some time. However it is only very recently that the concept has reached some common meaning accepted by the analysts’ and the IT community. The new CX model depends on two previous facts: the expansion of the social media, and the impact of the new advanced features of mobile devices regarding brand-customer interaction. CXsers vs UXers First there is some need of disambiguity between User Experience and Customer Experience. User Experience -UX, is a much well established concept related with the design of user interactions for particular devices. UX people are interested on multiple touch points of digital interfaces while CX people are interested on all kind of interfaces including physical ones. UX is an evolution of Web Usability, while CX is a marketing concept. UX is an instrument of User Experience. CX in fact is all about Connections and Interactions. Connections Dan Draper, the creative director Mad Men, understands very well that to market effectively means to connect with people, and the best way to connect to people is to use the connections people have with other people: understanding Social Media connections and taking the customer pulse of customers on those medias, and are strong facilitators of CX strategies.  Interactions We can very simply define CX as the relationship that a customer establishes with a brand through multiple touch points (interactions, channels) through the entire life cycle of his relationship- direct or indirect with the brand. Interactions can be grouped on Customer Journeys through multiple touch points defined as the path a customer follows to achieve a goal. Processes A customer journey today usually starts at the moment he surfs the Web, then he takes a purchase decision; purchases the product;  request a particular service and finally recommends or do not recommends the product.  Customer Journeys are processes, and to analyze customer journeys there exists today a broad offering of modern Customer Journey tools very similar actually to the use cases or UML activity diagrams for IT systems design. As a summary CX is nothing more and nothing less than applying process analysis methods for better understanding how to create value through customer interactions across the multiple user´s touch points with the brand.

  • SQL Saturday 43 (Redmond, WA) Review

    - by BuckWoody
    Last Saturday (June 12th) we held a “SQL Saturday” (more about those here) event in Redmond, Washington. The event was held at the Microsoft campus, at the Mixer in our new location called the “Commons”. This is a mall-like area that we have on campus, and the Mixer is a large building with lots of meeting rooms, so it made a perfect location for the event. There was a sign to find the parking, and once there they had a sign to show how to get to the building. Since it’s a secure facility, Greg Larsen and crew had a person manning the door so that even late arrivals could get in. We had about 400 sign up for the event, and a little over 300 attend (official numbers later). I think we would have had a lot more, but the sun was out – and you just can’t underestimate the effect of that here in the Pacific Northwest. We joke a lot about not seeing the sun much, but when a day like what we had on Saturday comes around, and on a weekend at that, you’d cancel your wedding to go outside to play in the sun. And your spouse would agree with you for doing it. We had some top-notch speakers, including Clifford Dibble and Kalen Delany. The food was great, we had multiple sponsors (including Confio who seems to be at all of these) and the attendees were from all over the professional spectrum, from developers to BI to DBA’s. Everyone I saw was very engaged, and when I visited room-to-room I saw almost no one in the halls – everyone was in the sessions. I also saw a much larger Microsoft presence this year, especially from Dan Jones’ team. I had a great turnout at my session, and yes, I was wearing an Oracle staff shirt. I did that because I wanted to show that the session I gave on “SQL Server for the Oracle DBA” was non-marketing – I couldn’t exactly bash Oracle wearing their colors! These events are amazing. I can’t emphasize enough how much I appreciate the volunteers and how much work they put into these events, and to you for coming. If you’re reading this and you haven’t attended one yet, definitely find out if there is one in your area – and if not, start one. It’s a lot of work, but it’s totally worth it.       Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Oracle At QCon SF 2012

    - by Cassandra Clark - OTN
    Oracle Technology Network is a Platinum sponsor at QCon San Francisco.  (qconsf.com).  Don’t miss these great developer focused sessions: Shay ShmeltzerHow we simplified Web, Mobile and Cloud development for our own developers? - the Oracle StoryOver the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of thelargest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud baseddevelopment and deployment?  Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan SmithProject Lambda in Java 8Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun GuptaJSR 356: Building HTML5 WebSocket Applications in JavaThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The full conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more!  At the Oracle booth, we’ll also be covering: ·         Oracle ADF Mobile·         Oracle Developer Cloud Service·         Oracle ADF Essentials·         NetBeans Project Easel Lastly we’ll share the results of a short cloud survey at QConSF ater this week.  If you attended this year's Oracle OpenWorld and JavaOne conferences, it would be hard not to notice that Oracle is clearly "all-in" when it comes to the Cloud.  With Cloud computing being such a hot topic on many OTN members' minds, we'd like to know what you're doing in the cloud and invite you to take this short cloud survey.

  • Issues with LVM partition size in Server 13.04

  • directory with 980MB meta data, millions of files, how to delete it? (ext3)

    - by Alexandre
    Hello, So I'm stuck with this directory: drwxrwxrwx 2 dan users 980M 2010-12-22 18:38 sessions2 The directories contents is small - just millions of tiny little files. I want to wipe it from the filesystem but have been unable to. My first try was: find sessions2 -type f -delete and find sessions2 -type f -print0 | xargs -0 rm -f but had to stop because both caused escalating memory usage. At one point it was using 65% of the system's memory. So I thought (no doubt incorrectly), that it had to do with the fact that dir_index was enabled on the system. Perhaps find was trying to read the entire index into memory? So I did this (foolishly): tune2fs -O^dir_index /dev/xxx Alright, so that should do it. Ran the find command above again and... same thing. Crazy memory usage. I hurriedly ran tune2fs -Odir_index /dev/xxx to reenable dir_index, and ran to Server Fault! 2 questions: 1) How do I get rid of this directory on my live system? I don't care how long it takes, as long as it uses little memory and little CPU. By the way, using nice find ... I was able to reduce CPU usage, so my problem right now is only memory usage. 2) I disabled dir_index for about 20 minutes. No doubt new files were written to the filesystem in the meanwhile. I reenabled dir_index. Does that mean the system will not find the files that were written before dir_index was reenabled since their filenames will be missing from the old indexes? If so and I know these new files aren't important, can I maintain the old indexes? If not, how do I rebuild the indexes? Can it be done on a live system? Thanks!

  • Htpc aka "Media Center": cheap and *silent*?

    - by Unknown
    It may be me, or the place I live (Italy), but it seems pretty hard to get a build or a prebuilt nettop or a laptop that fits the need. I need something silent able to playback all h.264 fullhd content without stuttering, and well (and not loosing the hw acceleration because of softsubs...) silent not ugly silent and (possibly) cheap. I'm going the linux route, therefore i'm moving towards a cpu-based or nvida-integrated solution (i don't think ati hw accelerated playback - or the intel "hd" acceleration - is useable yet). Ion nettop; it's either the Acer Revo (but here it's incredibly pricey and it's hard to find the dualcore version) or the Asrock Ion 330, that in the current version is rated "silent" at 26Db. 26. Sounds pretty noisy to me!!! the previous version was even worse. was this product really aimed at htpc market?? the Dell Zino - i think it's ATI based unfortunately. Laptop: correct me if I'm wrong: sub 600€/$ units are quite loud under full load (because of the tiny fans). ULW laptops are indeed quite similar: tiniest fans = high pitched noise and the cpu still lacks power for non hd-accelerated video decoding Handmade build: little money can be saved with underpowered cpus, a low-midrange cpu would help in the case of non-hw-accelerated content the cases are quite pricey the PSU one has to get ranges between 100/150 €/$ minimum to keep the noise down a low-mid build, all included, sums up to over 650 €/$ for a still-looking-ugly-unit, without the blu-ray drive. Please help. What do you advise on this? ;) Am I ignoring laptops too much, maybe? Are low-priced Acers that noisy/high pitched under full load?

  • Ripping CD Audio simultaneously from 2 drives on one PC via USB or PATA - rip accuracy preserved?

    - by Rob
    I'm considering ripping audio (reading audio) from CDs using 2 drives simultaneously to speed up the process of ripping the CDs - i.e. 2 at a time rather than 1. Are there any issues with achieving maximum rip accuracy? In general I wondered if people have tried this and if the simultaneous streams from both rip activities would overload the host machine and cause packet loss or read retries resulting in a sub-standard CD-DA Audio CD rip? If it just means the rip is slightly slower (but still faster than sequentially doing one rip followed by another) but still of maximum accuracy then that is OK for me. I will be using dbPowerAmp to rip the CDs and converting to FLAC lossless format. Specific examples: There are 2 machines I intend to do it on: A Toshiba NB100 1.6Ghz Atom netbook, 2Gb RAM, running Windows XP Home with 1 external LG DVD/CD burner and external 1 LG Blu-ray burner attached via USB 2.0, ripping to the machine's 5400rpm internal hard drive. This rips from one CD drive very well, more than adequate, it is a nippy, fast little machine for its specification. A Desktop PC running Windows 7 Home Premium with MSI P4M900M2-L/ MS-7255v2.0 motherboard and 1.86Ghz Intel Core 2 Duo E6320, 7200rpm hard drive and 2Gb RAM, with an internal LG PATA DVD/CD burner (master) and a Philips DVD/CD burner (slave) on the same PATA bus (perhaps separate buses would be another option to consider here). Thoughts?

  • Is my dns server being attacked? And what should I do about it?

    - by Mnebuerquo
    I've been having some intermittent dns problems with a web server, where certain isp's dns servers don't have my hostnames in cache and fail to look them up. At the same time, queries to opendns for those hostnames resolve correctly. It's intermittent, and it always works fine for me, so it's hard to identify the problem when someone reports connectivity problems to my site. In trying to figure this out, I've been looking at my logs to see if there are any errors I should know about. I found thousands of the following messages in my logs, from different ip's, but all requesting similar dns records: May 12 11:42:13 localhost named[26399]: client 94.76.107.2#36141: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#29075: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#47924: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#4727: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#16153: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#40267: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63507: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63721: query (cache) 'burningpianos.org/MX/IN' denied May 12 11:43:36 localhost named[26399]: client 82.209.240.241#3537: query (cache) 'burningpianos.com/MX/IN' denied I've read of Dan Kaminski's dns cache poisoning vulnerability, and I'm wondering if these log records are an attempt by some evildoer to attack my dns server. There are thousands of records in my logs, all requesting "burningpianos", some for com and some for org, most looking for an mx record. There are requests from multiple ip's, but each ip will request hundreds of times per day. So this smells to me like an attack. What is the defense against this?

  • Keep-Alive header not sent from Tomcat 5.5 http connector?

    - by Codek
    We're currently using a hardware load balancer, which then goes to Apache and that then goes to Tomcat 5.5 via the AJP connector. We've decided to dump apache for various reasons - In our current system it doesnt provide any advantage. However when I look at the headers sent when we do this, the "Keep-Alive: timeout=15 max=96" header doesnt get sent when you use the tomcat http connector Interestingly, i can find no documentiation on "keepalivetimeout" for tomcat5.5, but i can for tomcat6. But neither can i find evidence that tomcat5.5 doesnt support this setting. here's my connector: <Connector port="8090" maxHttpHeaderSize="8192" maxThreads="400" minSpareThreads="150" maxSpareThreads="300" enableLookups="false" connectionTimeout="2" maxKeepAliveRequests="400" disableUploadTimeout="true" /> So; Is there any way I can specify the keepalive timeout if we use the http connector with tomcat 5.5, and force this header entry to be sent? Just to be clear - the exact header entry i see back from the server is this with apache: Keep-Alive: timeout=2, max=100 But nothing from tomcat/coyote. I've looked at this some more, and I dont think the Keep-Alive header entry really matters. The problem seems to be that keep-alives are simply not supported in tomcat 5.5 http connector? They do seem to work in tomcat6 (+java 6). Thanks, Dan

  • Identify differences between MP3 files

    - by Thingomy
    I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.

  • Slow boot for OS and external devices

    - by Derek Van Cuyk
    I have been having this problem intermittently but as of yesterday, it has become more consistent. It originally started when I rebooted my PC at home and the OS (Windows 8) sat in a loop appearing to do nothing while loading. I figured since this was a new installation, that something may have just become corrupted and I decided to reinstall. So I tried to boot off of the thumb drive which had the installation iso and encountered pretty much the same issue. Same with the DVD drive. So, I rebooted once again and left it to load the entire night just to see if it ever would and sure enough this morning, Windows had finally loaded. Authentication had the same roblem albeit not quite as long (took about 5 minutes to authenticate). However, once I was in, everything appeared to be working fine and as quick as normal with the exception of when I tried to scan the C drive for any errors, which ran unbearably slow (45 minutes and before I left for work and was not finished scanning a 64GB SSD drive). I mention that I have had this issue but never when loading the OS. Before it occurred when trying to install windows 7 from a different DVD drive than the one I have now. It took me about 3 hours to do it since I had to wait sometimes 30+ min for each step to finish processing. Does anyone have an idea as to what can cause this? I am assuming it is the motherboard since it is responsible for communication with all the devices I'm having issues with but I cannot find anyone else who has had a problem like this and don't want to drop more money on a MB if it isn't the problem. Hardware: Motherboard: Asus M4A78T-E Socket AM3/ AMD 790GX/ Hybrid CrossFireX Hard Drive: Kingston SSDNow V+180 64GB Micro SATA II 3GB/S 1.8 Inch Solid State Drive SVP180S2/64G Optical Drive: Samsung Blu-Ray Combo Internal 12XReadable and DVD-Writable Drive with Lightscribe SH-B123L/BSBP Thanks, Derek

  • AVCHD MTS h264 1080p file with choppy playback in Linux

    - by marc
    When I'm trying play video files from my camera: Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1) -> 50.00 (50/1) Input #0, mpegts, from '00027.MTS': Duration: 00:00:38.88, start: 2.884289, bitrate: 16945 kb/s Program 1 Stream #0.0[0x1011]: Video: h264 (High), yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 50 tbc Stream #0.1[0x1100]: Audio: ac3, 48000 Hz, stereo, s16, 256 kb/s … on my Linux computer (Ubuntu 12.04), I get choppy playback. It's completly unusable... I tried: Totem VLC mplayer The result is always same issue. I sent the same video file to a friend who has ubuntu 10.04 to test, and he also has the same issue. He has Windows 7, and confirms that on Windows, the video work well. I have an Intel® Core™2 CPU 6300 @ 1.86GHz × 2 with GF 9600 GT, with closed NVIDIA drivers. This is not any kind of issue with big files playing slow from an HDD issue. I have an SSD drive! I spent the last days and nights, trying hundreds of commands for ffmpeg, handbrake, mencoder... Any of them won't let me create a file with enough quality. I downloaded few movies from YouTube in 1080p, and playback worked well without any big pixels and choppiness. I would like have highest possible quality, I will put following files onto a Blu-ray disk so I don't need to compress them to get a smaller size. I just want smoth playback on my Linux box. On Windows, the same file is working well.

  • Managing per-user rc.d init scripts

    - by Steve Schnepp
    I want to delegate SysV init scripts to each user. Like the SysV init, each item in ${HOME}/rc.d starting with S will be launched on server start-up with the start argument. The same for the server shut-down with the one starting with K and with the stop argument. I thought about scripting it myself, but maybe there is already some kind of implementation out there1. In summary it would be a script in /etc/init.d/ that iterates through all the users and launches runparts as the user on the relevant scripts. The platform here is a Linux (Debian flavour), but I think the solution would be quite portable among various Unix-like platforms. Update: The point here is for users to be able to create their own init scripts that should be launch on their behalf when the system boots up. As Dan Carley pointed out, the services won't be able to access any system asset (priviledged ports, system logs, ...). 1. This way I don't have to think that much about all the subtle security implications such as script timeouts for example...

  • Troubleshooting wireless client-bridged networks between two DD-WRT routers?

    - by KronoS
    I recently purchased a Buffalo N600 wireless router which came with DD-WRT pre-installed. I want to take my old wireless router a Linksys WRT54GL, also with DD-WRT pre-installed, and use it as a wireless bridge for my HTPC and Blu-Ray Player in the other room. I other words, I'm trying to connect to WIRED networks via the wireless on the routers. I followed eactly the instruction from DD-WRT's manual for 'Client Bridged' however I'm still not able to connect to two routers correctly, when the encryption is enabled (WPA2-Personal Mixed) however I am able to connect the two routers when there is NO encryption. I've checked, double checked, and triple checked that EVERYTHING is the same on BOTH routers: Routers 1 & 2 Encryption: WPA2-Personal Mixed Wireless Mode: G-Only Wireless Channel: 6 Subnet Mask: 255.255.255.0 Subnet: 192.168.1.0/254 SSID: Krono$ Primary Router #1 (Buffalo N600) IP Address: 192.168.1.1 Firewall: Enables w/ defaults DCHP: Enabled as DHCP Server Secondary Router #2 (Linksys WRT54GL) IP Address: 192.168.1.2 Firewall: Disabled as per DD-WRT instructions I'm looking for any configurations that I may have missed, or settings that may need to happen in order for this work.

  • Why do manufacturers not show all hardware power usage?

    - by Drew
    I find it slightly more difficult to build a computer when I do not know how much power is needed for a component. When selecting a power supply for a computer, it is difficult to know how large of one to get. You don't want to go too large for cost reasons and circuit reasons, but you don't want to go too low and not be able to properly use every component. For instance, a graphics card might say "Minimum of a 500 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 30 Amps.)" But it really needs 360W (12V * 30A). So why don't they just say "Uses 360W max and xxxW peak"? Processors, I have noticed are good at reporting their power usage, but aside from processors and sometimes graphics cards, power usage is easily found. What is the power consumed by the Blu-ray / DVD drives? By the HDDs/SSDs? By the Mobo? etc. Why are these questions not easily answered when building a machine?

  • Important hardware components to avoid bottlenecks/improve speed on a laptop?

    - by joelhaus
    Looking for a powerful general use (including web development) laptop running Windows. Price points seem to be all over the place. Many less powerful machines are priced much higher than machines with better specs. How does one navigate this market? Are there any unpublished/under-publicized specs/bottlenecks you look for? Understanding that hardware improves over time, is there an efficient ratio that can be used (or something similar, like Windows Experience Index?) which will indicate how powerful a system is? Thanks in advance! P.S. Here is an example from a laptop released on September 17, 2010. Can anyone pick apart these specs? Is there missing information you would be looking for? OS: Win 7 Display: 16.4" LED backlit Processor: Intel Core i7-740QM, 6MB L3 Cache RAM: 6GB DDR3 1333MHz (8GB max.) Graphics: NVIDIA GeForce GT 425M (1 GB of dedicated DDR3) HDD: 500GB 7200RPM SATA Hard Drive Removable Disc: Blue-ray with DVD±R/RW Misc: webcam/mic/speakers/bluetooth (via Sony Vaio VPC-F137FX/B)

  • Denying access to website via htaccess based on http header

    - by neekster
    I've been trying for ages to get this to work and I can't put my finger on it. What I'm trying to do is block access to a site from a number of countries, based on the CF-IPCountry header added by CloudFlare. I figured htaccess was a suitable way to do this. We are running LiteSpeed 4.2.4 on top of DirectAdmin for a control panel. The problem we having is the htaccess rule doesn't seem to do anything. Here's the rule we tried: SetEnvIf CF-IPCountry AU UnwantedCountry=1 Order allow,deny Deny from env=UnwantedCountry Allow from all That makes no difference at all, connections are still accepted. Just to check that the rule was at least being processed, I changed Allow from all to Deny from all, and connections were refused. So it appears to be a problem wit the variable. Here's the relevant headers that come in with the request. Connection: Keep-Alive Accept-Encoding: gzip CF-Connecting-IP: xx.xx.xx.xx CF-IPCountry: AU X-Forwarded-For: xx.xx.xx.xx.xx CF-RAY: c9062956e2d04b6 X-Forwarded-Proto: http CF-Visitor: {"scheme":"http"} Zone-Name: xx.com.au Hopefully someone can help me out, this has been driving me nuts for too long. Thanks

  • Extending a home wireless network using two routers running tomato

    - by jalperin
    I have two Asus RT-N16 routers each flashed with Tomato (actually Tomato USB). UPSTAIRS: Router 'A' (located upstairs) is connected to the internet via the WAN port and connected via a LAN port to a 10/100/1000 switch (Switch A). Several desktops are also attached to Switch A. Router A uses IP 192.168.1.1. DOWNSTAIRS: I've just acquired Router 'B' and set it to IP 192.168.1.2. I have a cable running from Switch A downstairs to another switch (Switch B). Tivo, a blu-ray player and a Mac are connected to Switch B. My plan was to connect Router B to Switch B so that I have improved wireless access downstairs. (The wireless signal from Router A gets weak downstairs in a number of locations.) How should I configure Router B so that all devices in the house can see and talk to one another? I know that I need to change DHCP on Router B so that it doesn't cover the same range as DHCP on Router A. Should I be using WDS on the two routers, or is that unnecessary since I already have a wired connection between the two routers? Any other thoughts or suggestions? Thanks! --Jeff

  • File corruption (bad checksums) in large files copied to VMware guest

    - by AllanA
    In setting up a development lab, I've got a desktop system running ESXi 4.1.0 (free license) on SATA RAID 0 (already purchased and configured when I started this job; I'm open to hardware input as it pertains to my problem.) Its guests so far include two Win2008 Server R2 64-bit VMs and on Ubuntu 10.04 64-bit VM. I'm installing onto the Windows servers. We've been copying off some fairly large files (over a gigabyte) for an installation, hoping to install more quickly from a (virtual) hard drive than from the network for from BD-ROM. The problem is that they keep coming up with different checksums from the originals. The file sizes are the same, but md5sum reports different numbers (and so does the installer, as it refuses to continue when the checksums don't match.) I've tried copying directly from the BD-ROM (attaching the OS drive to the host system's physical drive). I've tried copying the large files onto a co-worker's Windows machine from his Blu-Ray drive; when I do that, the checksums match. But when I copy from his machine to the VM guest over a network share, the checksums no longer match. Thinking this meant a corrupt destination drive, I deleted it in vSphere and added another freshly created drive. The problem persists. I'm not sure what to try next.
